Descriptions

In the function gf_hevc_read_pps_bs_internal function in media_tools/av_parsers.c in GPAC 1.0.1 there is a loop, which with crafted file, pps->num_tile_columns may be larger than sizeof(pps->column_width), which results in a heap overflow in the loop.

En la función gf_hevc_read_pps_bs_internal en el archivo media_tools/av_parsers.c en GPAC versión 1.0.1 se presenta un bucle, que con el archivo diseñado, pps-)num_tile_columns puede ser mayor que sizeof(pps-=column_width), el cual resulta en un desbordamiento de la pila en el bucle
